The rubber pneumatic butterfly valve teaches you the key points to pay attention to when installing the pump pneumatic butterfly valve?
The rubber pneumatic butterfly valve teaches you the key points for installing the pump pneumatic butterfly valve:
1. The rubber damping pad is arranged in a single layer. If the frequency ratio cannot meet the request, multi-layer series arrangement can be adopted, but the number of damping pads should not be more than five layers. The model, number, area and rubber hardness of each layer of rubber vibration isolation pads set in series shall be intact and different.
2. The pad and steel plate shall be bonded with adhesive. The plane size of galvanized steel plate shall be 10mm larger than each end of rubber damping pad. Rubber damping pads bonded on the upper and lower layers of galvanized steel plate shall be staggered.
3. Before construction and installation, timely inspection shall be carried out. During installation, the static shrinkage deformation of damping elements shall not exceed the maximum allowable value.
4. When installing the water pump unit, the supporting air of the installed water pump unit shall be flat and have sufficient bearing ability.
5. The vibration damping elements of the unit shall avoid contact with acids, alkalis, organic solvents and other substances.
6. The damping elements shall be symmetrically arranged according to the central axis of the pump unit. The plane layout of the rubber damping pad can be arranged clockwise or counterclockwise.
7. When six supporting points are used for the vibration damping elements of the unit, four of them are arranged at the four corners of the inertia block or the section steel frame, and the other two should be set on the long side line, and their positions should be adjusted so that the compression deformation of the vibration damping elements is as different as possible.
8. When rubber shock pad or damping spring shock absorber is installed for vibration reduction of horizontal pump unit, under normal circumstances, the rubber shock pad and damping spring shock absorber need not be bonded or fixed with the air, or with the inert block or steel frame.
9. The edge line of the rubber damping pad shall not exceed the edge line of the inert block; The bearing area of the section steel frame shall not be less than that of the top of the damping element.
10. When rubber shock absorber is used for vibration reduction installation of vertical water pump unit, it is better to set steel frame under the base of water pump unit and adopt anchoring installation; The section steel base and rubber shock absorber shall be fixed with bolts (with spring washers). Anchor bolts are set in the air or floor, and the rubber shock absorber is fixed in the air or floor after passing the anchor bolts.

Normal operation and device request of bellows rotary compensator
Bellows compensator can be used for flexible connection between storage tank and pipeline. In recent years, the storage tanks in oil fields, oil depots, and chemical plants have become larger and larger. Due to the limitation of geological conditions, the natural subsidence of the foundation causes the location changes of the storage tanks and the inlet and outlet pipelines, which is easy to form damage to the connecting pipelines and tank walls. Therefore, corrugated contraction joints or pneumatic butterfly valves are installed in the inlet and outlet pipelines of the storage tanks to compensate for the displacement. A small pull rod type (multiple universal type) corrugated contraction joint is installed in the outlet pipeline of the storage tank. It can not only absorb the axial displacement caused by the thermal contraction of the pipeline, but also compensate the lateral displacement caused by the tank bottom subsidence, avoid the damage of the pipeline and the tank wall, and also has a certain anti shock and seismic effect.
The bellows compensator is used as a flexible coupling pipe for the pump on the inlet and outlet pipelines of the pump. Universal (i.e. universal) contraction joints are installed on the inlet and outlet pipelines of the pump to compensate for the thermal contraction of the pipeline, reduce the thrust of the pipeline thermal contraction on the pump, or absorb the vibration caused by the pump operation.
